Where are core temperature receptors primarily located?

Core temperature receptors are primarily located in the hypothalamus, which is the body's thermostat. The hypothalamus plays a crucial role in thermoregulation, helping to maintain a stable internal body temperature. It receives input from peripheral receptors and adjusts physiological responses, such as sweating or shivering, to either dissipate heat or generate warmth when necessary. This feedback mechanism is essential for maintaining homeostasis in the body.

The brainstem does have regulatory functions related to temperature, but it does not serve as the primary center for core temperature regulation. The pituitary gland is involved in numerous hormonal functions but is not directly responsible for monitoring temperature. The spinal cord may have some indirect role in reflex actions related to temperature responses, but it does not contain the primary receptors for core temperature.
